Zarya, the International Space Station’s first component to go into
space, passed the 50,000th orbit mark at 11:17 a.m. EDT today. Zarya,
which is Russian for “Sunriseö, was funded by the United States and
built by Russia. It launched atop a Proton rocket from Baikonur
Cosmodrome in Kazakhstan on Nov. 20, 1998.
Just before Zarya made its mark in the history books, STS-118 and
Expedition 15 crew members used Canadian-built robotic arms to attach a
third stowage platform on to the international outpost’s exterior. They
used Space Shuttle Endeavour’s robotic arm to lift external stowage
platform-3 out of the orbiter payload bay and hand it off to the station
arm for installation on the Port 3 truss segment.
The new platform is the second component attached to the station since
Endeavour and the STS-118 crew arrived Aug. 10. STS-118 spacewalkers
installed the Starboard 5 (S5) truss segment on to the end of the
Starboard 4 (S4) truss segment on Saturday. The S5 will serve as a
spacer segment between the S4 and Starboard 6 (S6) segments. The S6 and
its solar arrays will be attached during a future shuttle mission.
During the second STS-118 spacewalk, astronauts replaced a failed
control moment gyroscope in the Z1 truss. The station has four
gyroscopes that control its orientation in orbit.
Two more spacewalks are slated for the remainder of STS-118’s stay. The
next is slated to take place Wednesday and will focus on preparing the
Port 6 truss for relocation from atop the Destiny laboratory module to
the end of the Port 5 truss when STS-120 visits later this year.
In other activities, the two crews have been transferring cargo between
Endeavour and the station. STS-118’s stay at the station is slated to
wrap up when Endeavour undocks Aug. 20.
